zeromq: updated to 4.3.5 libzmq 4.3.5 Relicensing from LGPL-3.0+ (with custom exceptions) to MPL-2.0 is now complete. libzmq is now distributed under the Mozilla Public License 2.0. Relicensing grants have been collected from all relevant authors, and some functionality has been clean-room reimplemented where that was not possible. In layman terms, the new license provides the same rights and obligations as before. Source files are now tagged using the SPDX license identifier format. Details of the relicensing process can be seen at: Relicensing grants have been archived at: https://github.com/rlenferink/libzmq-relicense A special thanks to everybody who helped with this long and difficult task, with the process, the reimplementations, the collections and everything else. New DRAFT (see NEWS for 4.2.0) socket options: ZMQ_BUSY_POLL will set the SO_BUSY_POLL socket option on the underlying sockets, if it is supported. ZMQ_HICCUP_MSG will send a message when the peer has been disconnected. ZMQ_XSUB_VERBOSE_UNSUBSCRIBE will configure a socket to pass all unsubscription messages, including duplicated ones. ZMQ_TOPICS_COUNT will return the number of subscribed topics on a PUB/SUB socket. ZMQ_NORM_MODE, ZMQ_NORM_UNICAST_NACK, ZMQ_NORM_BUFFER_SIZE, ZMQ_NORM_SEGMENT_SIZE, ZMQ_NORM_BLOCK_SIZE, ZMQ_NORM_NUM_PARITY, ZMQ_NORM_NUM_AUTOPARITY and ZMQ_NORM_PUSH to control various aspect of NORM sockets. See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details. New DRAFT (see NEWS for 4.2.0) zmq_ppoll APIs was added that differs from zmq_poll in the same way that ppoll differs from poll. See doc/zmq_ppoll.txt for details. Various bug fixes and performance improvements.

Security advisories:
CVE-2020-15166: Denial-of-Service on CURVE/ZAP-protected servers by
unauthenticated clients.
If a raw TCP socket is opened and connected to an endpoint that is fully
configured with CURVE/ZAP, legitimate clients will not be able to exchange
any message. Handshakes complete successfully, and messages are delivered to
the library, but the server application never receives them.
For more information see the security advisory:
GHSA-25wp-cf8g-938m
Stack overflow on server running PUB/XPUB socket (CURVE disabled).
The PUB/XPUB subscription store (mtrie) is traversed using recursive
function calls. In the remove (unsubscription) case, the recursive calls are
NOT tail calls, so even with optimizations the stack grows linearly with the
length of a subscription topic. Topics are under the control of remote
clients - they can send a subscription to arbitrary length topics. An
attacker can thus cause a server to create an mtrie sufficiently large such
that, when unsubscribing, traversal will cause a stack overflow.
For more information see the security advisory:
GHSA-qq65-x72m-9wr8
Memory leak in PUB server induced by malicious client(s) without CURVE/ZAP.
Messages with metadata are never processed by PUB sockets, but the metadata
is kept referenced in the PUB object and never freed.
For more information see the security advisory:
GHSA-4p5v-h92w-6wxw
Memory leak in client induced by malicious server(s) without CURVE/ZAP.
When a pipe processes a delimiter and is already not in active state but
still has an unfinished message, the message is leaked.
For more information see the security advisory:
GHSA-wfr2-29gj-5w87
Heap overflow when receiving malformed ZMTP v1 packets (CURVE disabled).
By crafting a packet which is not valid ZMTP v2/v3, and which has two
messages larger than 8192 bytes, the decoder can be tricked into changing
the recorded size of the 8192 bytes static buffer, which then gets overflown
by the next message. The content that gets written in the overflown memory
is entirely decided by the sender.
For more information see the security advisory:
GHSA-fc3w-qxf5-7hp6
Note for packagers: an external, self-contained sha1 library is now
included in the source tree under external/sha1/ - it is licensed
under BSD-3-Clause and thus it is fully compatible with libzmq's
license.
It is only used if WebSockets support is enabled, and if neither GnuTLS nor
NSS are available.
Note for packagers: an internal reimplementation of strlcpy is now included,
for wider platform compatibility.
libbsd can be used and is enabled by default if available instead of the
internal implementation, for better security maintenance in distros.
Note for packagers: ZeroMQConfig.cmake is now installed in the arch-dependent
subdirectory - eg: /usr/lib/x86_64-linux-gnu/cmake/
New DRAFT (see NEWS for 4.2.0) socket type:
ZMQ_CHANNEL is a thread-safe alternative to ZMQ_PAIR.
See doc/zmq_socket.txt for details.
New DRAFT (see NEWS for 4.2.0) socket option:
ZMQ_ONLY_FIRST_SUBSCRIBE will cause only the first part of a multipart
message to be processed as a subscribe/unsubscribe message, and the rest
will be forwarded as user data to the application.
ZMQ_RECONNECT_STOP will cause a connecting socket to stop trying to
reconnect in specific circumstances. See the manpage for details.
ZMQ_HELLO_MSG to set a message that will be automatically sent to a new
connection.
ZMQ_DISCONNECT_MSG to set a message that will be automatically received when
a peer disconnects.
See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
New DRAFT (see NEWS for 4.2.0) zmq_ctx_get_ext/zmq_ctx_set_ext APIs were added
to allow enhancing the context options with variable data inputs.
See doc/zmq_ctx_get_ext.txt and doc/zmq_ctx_set_ext.txt for details.
New DRAFT (see NEWS for 4.2.0) transport options WS and WSS added for support
of WebSockets (and secure WebSockets via TLS) via the ZWS 2.0 protocol.
WSS requires the GnuTLS library for TLS support. ZMQ_WSS_ specific socket
options were added to support TLS.
WebSockets support is disabled by default if DRAFT APIs are disabled.
New DRAFT (see NEWS for 4.2.0) socket type, PEER, which is thread safe and a
related zmq_connect_peer function which atomically and thread-safely connects
and returns a routing-id.
New DRAFT (see NEWS for 4.2.0) zmq_msg_init_buffer API was added to allow
the construction of a message by copying from an existing buffer.
New DRAFT (see NEWS for 4.2.0) zmq_poller_size API was added to allow querying
the number of sockets/fds registered in a zmq_poller.
ZMTP 3.1 peers will receive subscribe/cancel on PUB/SUB via commands rather
than using the first byte of the payload.
zmq_z85_decode now checks that the input string's length is at least 5
characters
and always a multiple of 5 as per API specification.

zeromq: updated to 4.3.2 libzmq 4.3.2 CVE-2019-13132: a remote, unauthenticated client connecting to a libzmq application, running with a socket listening with CURVE encryption/authentication enabled, may cause a stack overflow and overwrite the stack with arbitrary data, due to a buffer overflow in the library. Users running public servers with the above configuration are highly encouraged to upgrade as soon as possible, as there are no known mitigations. All versions from 4.0.0 and upwards are affected. Thank you Fang-Pen Lin for finding the issue and reporting it! New DRAFT (see NEWS for 4.2.0) zmq_socket_monitor_versioned API that supports a versioned monitoring events protocol as a parameter. Passing 1 results in the same behaviour as zmq_socket_monitor. Version 2 of the events protocol allows new events, new metadata, different socket types for the monitors and more. It is described in details in doc/zmq_socket_monitor_versioned.txt New DRAFT (see NEWS for 4.2.0) zmq_socket_monitor_pipes_stats that triggers a new ZMQ_EVENT_PIPES_STATS to be delivered via zmq_socket_monitor_versioned v2 API, which contains the current status of all the queues owned by the monitored socket. See doc/zmq_socket_monitor_versioned.txt for details. New DRAFT (see NEWS for 4.2.0) zmq_poller_fd that returns the FD of a thread safe socket. See doc/zmq_poller.txt for details. New DRAFT (see NEWS for 4.2.0) socket options: ZMQ_XPUB_MANUAL_LAST_VALUE is similar to ZMQ_XPUB_MANUAL but allows to avoid duplicates when using last value caching. ZMQ_SOCKS_USERNAME and ZMQ_SOCKS_PASSWORD that implement SOCKS5 proxy authentication. See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details. Implemented background thread names for Windows, when the Visual Studio debugger is being used. Fixed 3358 - test_security_zap failing due to SIGBUS on SPARC64, hard-coded IPC socket binds in tests cause race conditions Fixed 3361 - enabling GSSAPI support (when using autools) does not work due to regression introduced in 4.2.3 Fixed 3362 - remove documentation for ZMQ_THREAD_PRIORITY context option getter, it's not implemented Fixed 3363 - tests fail to build due to stricter compiler printf validation in new versions of GCC Fixed 3367 - try to infer cacheline size at build time, first with getconf LEVEL1_DCACHE_LINESIZE, and then by reading /sys/devices/system/cpu/cpu0/cache/index0/coherency_line_size (autoconf only), and only then falling back to the previous default of 64 bytes. Avoids false sharing on POWER and s390x. Import ax_func_posix_memalign.m4 as a more reliable check for posix_memalign presence on some unix platforms. Prefer c++11 atomic primitives to compiler intrinsics, when both are available, as the former is more reliable. Set test_pair_ipc and test_rebind_ipc to XFAIL on GNU/Hurd due to non-functioning getsockname on AF_UNIX. Fixed 3370 - Make queue length and HWM state observable Fixed 3373 - performance regression in zmq_poll on CentOS 6/7 Fixed 3375 - assign names to all pthreads created by the library to ease debugging Fixed 3376 - assigned random TIPC port is not returned by ZMQ_LAST_ENDPOINT Fixed 3385 - TCP port in ZMQ_LAST_ENDPOINT depends on global locale Fixed 3404 - use std::condition_variable_any when possible Fixed 3436 - reconnect interval exponential backoff and may lead to integer overflows Fixed 3440 - improve zmq_proxy performance by batching of up to 1000 consecutive messages (if any) and add perf/proxy_thr tool Fixed 3451 - fix support of /dev/poll on Solaris Fixed 3452 - strnlen may not be available Fixed 1462 - test failure in test_filter_ipc due to invalid system groups Fixed 3269 - Boost.ASIO integration stopped working with v4.3.0 Fixed 3479 - ZeroMQ does not build for QNX 6.6 with CMake Fixed 3481 - add include to fix uClibc++ compilation Fixed 3491 - build broken on Fedora 30 Fixed 3494 - ZeroMQConfig.cmake fails if shared libraries are not built Fixed 3498 - syntax error on Windows related to socket descriptor type Fixed 3500 - PLAIN HELLO message incorrectly uses WELCOME literal, regression introduced in 4.3.0 Fixed 3517 - configure errors because of syntax errors in the use of test shell command Fixed 3521 - document how to achieve high performance with the PGM transport Fixed 3526 - failure case behavior unclear in zmq_msg_send documentation Fixed 3537 - fix build on z/OS by using pthread_equal instead of comparing variables directly Fixed 3546 - CMake links with librt on MinGW which is not available Many coding style, duplication, testing and static analysis improvements.
zeromq: updated to 4.3.1
0MQ version 4.3.1 stable:
* CVE-2019-6250: A vulnerability has been found that would allow attackers to
direct a peer to jump to and execute from an address indicated by the
attacker.
This issue has been present since v4.2.0. Older releases are not affected.
NOTE: The attacker needs to know in advance valid addresses in the peer's
memory to jump to, so measures like ASLR are effective mitigations.
NOTE: this attack can only take place after authentication, so peers behind
CURVE/GSSAPI are not vulnerable to unauthenticated attackers.
See https://github.com/zeromq/libzmq/issues/3351 for more details.
Thanks to Guido Vranken for uncovering the issue and providing the fix!
* Note for packagers: as pkg-config's Requires.private is now used to properly
propagate dependencies for static builds, the libzmq*-dev or zeromq-devel or
equivalent package should now depend on the libfoo-dev or foo-devel packages
of all the libraries that zmq is linked against, or pkg-config --libs libzmq
will fail due to missing dependencies on end users machines.
0MQ version 4.3.0 stable:
* The following DRAFT APIs have been marked as STABLE and will not change
anymore:
- ZMQ_MSG_T_SIZE context option (see doc/zmq_ctx_get.txt)
- ZMQ_THREAD_AFFINITY_CPU_ADD and ZMQ_THREAD_AFFINITY_CPU_REMOVE (Posix only)
context options, to add/remove CPUs to the affinity set of the I/O threads.
See doc/zmq_ctx_set.txt and doc/zmq_ctx_get.txt for details.
- ZMQ_THREAD_NAME_PREFIX (Posix only) context option, to add a specific
integer prefix to the background threads names, to easily identify them.
See doc/zmq_ctx_set.txt and doc/zmq_ctx_get.txt for details.
- ZMQ_GSSAPI_PRINCIPAL_NAMETYPE and ZMQ_GSSAPI_SERVICE_PRINCIPAL_NAMETYPE
socket options, for the corresponding GSSAPI features. Additional
definitions for principal name types:
- ZMQ_GSSAPI_NT_HOSTBASED
- ZMQ_GSSAPI_NT_USER_NAME
- ZMQ_GSSAPI_NT_KRB5_PRINCIPAL
See doc/zmq_gssapi.txt for details.
- ZMQ_BINDTODEVICE socket option (Linux only), which will bind the
socket(s) to the specified interface. Allows to use Linux VRF, see:
https://www.kernel.org/doc/Documentation/networking/vrf.txt
NOTE: requires the program to be ran as root OR with CAP_NET_RAW
- zmq_timers_* APIs. These functions can be used for cross-platforms timed
callbacks. See doc/zmq_timers.txt for details.
- The following socket monitor events:
- ZMQ_EVENT_HANDSHAKE_FAILED_NO_DETAIL: unknown errors during handshake.
- ZMQ_EVENT_HANDSHAKE_SUCCEEDED: Handshake completed with authentication.
- ZMQ_EVENT_HANDSHAKE_FAILED_PROTOCOL: Protocol errors with peers or ZAP.
- ZMQ_EVENT_HANDSHAKE_FAILED_AUTH: Failed authentication requests.
See doc/zmq_socket_monitor.txt for more details and error codes.
- zmq_stopwatch_intermediate which returns the time elapsed without stopping
the stopwatch.
- zmq_proxy_steerable command 'STATISTICS' to retrieve stats about the amount
of messages and bytes sent and received by the proxy.
See doc/zmq_proxy_steerable.txt for more information.
* The build-time configuration option to select the poller has been split, and
new API_POLLER (CMake) and --with-api-poller (autoconf) options will now
determine what system call is used to implement the zmq_poll/zmq_poller APIs.
The previous POLLER and --with-poller options now only affects the
internal I/O thread. In case API_POLLER is not specified, the behaviour keeps
backward compatibility intact and will be the same as with previous releases.
* The non-default "poll" poller for the internal I/O thread (note: NOT for the
zmq_poll/zmq_poller user APIs!) has been disabled on Windows as WSAPoll does
not report connection failures. For more information see:
- https://daniel.haxx.se/blog/2012/10/10/wsapoll-is-broken/
- https://curl.haxx.se/mail/lib-2012-10/0038.html
- https://bugs.python.org/issue16507
* New epoll implementation for Windows, using the following implementation:
https://github.com/piscisaureus/wepoll/tree/v1.5.4
To use this, select "epoll" as the poller option in the build system.
Note for distributors: the wepoll source code is embedded and distributed.
It is licensed under the BSD-2-Clause and thus it is compatible with LGPL-3.0.
Note that, if selected at build time, the license text must be distributed
with the binary in accordance to the license terms. A copy can be found at:
external/wepoll/license.txt
* The pre-made Visual Studio solutions file are deprecated, and users are
encouraged to use the CMake solution generation feature instead.
* New DRAFT (see NEWS for 4.2.0) socket options:
- ZMQ_ROUTER_NOTIFY to deliver a notification when a peer connects and/or
disconnects in the form of a routing id plus a zero-length frame.

zeromq: updated to 4.2.5
0MQ version 4.2.5 stable:
* Fixed 3018 - fix backward-incompatible change in the NULL auth
mechanism that slipped in 4.2.3 and made connections
with a ZAP domain set on a socket but without a working
ZAP handler fail. See ZMQ_ZAP_ENFORCE_DOMAIN and RFC27.

zeromq: Requires C99.
zeromq: updated to 4.2.3
version 4.2.3 stable:
* API change: previously ZMQ_POLLOUT on a ZMQ_ROUTER socket returned always
true due to how the type works. When ZMQ_ROUTER_MANDATORY is set, sending
fails when the peer is not available, but ZMQ_POLLOUT always returns true
anyway, which does not make sense. Now when ZMQ_ROUTER_MANDATORY is set,
ZMQ_POLLOUT on a ZMQ_ROUTER will return true only if at least one peer is
available.
Given ZMQ_POLLOUT with ZMQ_ROUTER was not usable at all previously, we do
not consider this a breakage warranting a major or minor version increase.
* ZMQ_IDENTITY has been renamed to ZMQ_ROUTING_ID and ZMQ_CONNECT_RID has been
renamed to ZMQ_CONNTECT_ROUTING_ID to disambiguate. ZMQ_IDENTITY and
ZMQ_CONNECT_RID are still available to keep backward compatibility, and will
be removed in a future release after further advance notice.
* DRAFT API change: zmq_poller_wait, zmq_poller_wait_all and zmq_poller_poll
have been changed to be inline with other existing APIs that have a timeout
to return EAGAIN instead of ETIMEDOUT as the errno value.
* Existing non-DRAFT socket types ZMQ_REP/REQ, ZMQ_ROUTER/DEALER and
ZMQPUB/SUB, that were previously declared deprecated, have been reinstated
as stable and supported.
* Tweetnacl: add support for, and use preferably if available, getrandom() as
a simpler and less error-prone alternative to /dev/urandom on OSes where it
is available (eg: Linux 3.18 with glibc 2.25).
* Curve: all remaining traces of debug output to console are now removed, and
new DRAFT events are available to properly debug CURVE, PLAIN, GSSAPI and
ZAP events and failures. See below for details on the new events.
* New DRAFT (see NEWS for 4.2.0) socket options:
- ZMQ_GSSAPI_PRINCIPAL_NAMETYPE and ZMQ_GSSAPI_SERVICE_PRINCIPAL_NAMETYPE, for
the corresponding GSSAPI features. Additional definitions for principal
name types:
- ZMQ_GSSAPI_NT_HOSTBASED
- ZMQ_GSSAPI_NT_USER_NAME
- ZMQ_GSSAPI_NT_KRB5_PRINCIPAL
See doc/zmq_gssapi.txt for details.
- ZMQ_BINDTODEVICE (Linux only), which will bind the socket(s) to the
specified interface. Allows to use Linux VRF, see:
https://www.kernel.org/doc/Documentation/networking/vrf.txt
NOTE: requires the program to be ran as root OR with CAP_NET_RAW
- ZMQ_ZAP_ENFORCE_DOMAIN, enables strict RFC 27 compatibility mode and makes
the ZAP Domain mandatory when using security. See:
https://rfc.zeromq.org/spec:27/ZAP
See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
* New DRAFT (see NEWS for 4.2.0) context options:
- ZMQ_THREAD_AFFINITY_CPU_ADD and ZMQ_THREAD_AFFINITY_CPU_REMOVE (Posix only),
to add and remove CPUs to the affinity set of the I/O threads. Useful to pin
the background threads to specific CPUs.
- ZMQ_THREAD_NAME_PREFIX (Posix only), to add a specific integer prefix to the
background threads names, to easily identify them for debugging purposes.
See doc/zmq_ctx_set.txt and doc/zmq_ctx_get.txt for details.
* New DRAFT (see NEWS for 4.2.0) message property name definitions to facilitate
the use of zmq_msg_gets:
- ZMQ_MSG_PROPERTY_ROUTING_ID
- ZMQ_MSG_PROPERTY_SOCKET_TYPE
- ZMQ_MSG_PROPERTY_USER_ID
- ZMQ_MSG_PROPERTY_PEER_ADDRESS
See doc/zmq_msg_gets.txt for details.
* New DRAFT (see NEWS for 4.2.0) API zmq_socket_get_peer_state, to be used to
query the state of a specific peer (via routing-id) of a ZMQ_ROUTER socket.
* New DRAFT (see NEWS for 4.2.0) Socket Monitor events:
- ZMQ_EVENT_HANDSHAKE_FAILED_NO_DETAIL, unknown system error and returns errno
- ZMQ_EVENT_HANDSHAKE_SUCCEEDED, handshake was successful
- ZMQ_EVENT_HANDSHAKE_FAILED_PROTOCOL, protocol errors between peers or server
and ZAP handler. Returns one of ZMQ_PROTOCOL_ERROR_* - see manpage for list
- ZMQ_EVENT_HANDSHAKE_FAILED_AUTH, failed authentication, returns ZAP status
These events trigger when the ZMTP security mechanism handshake is
completed or failed. See doc/zmq_socket_monitor.txt for more information.
* New DRAFT (see NEWS for 4.2.0) zmq_proxy_steerable command 'STATISTICS' to
retrieve stats about the amount of messages and bytes sent and received by
the proxy. See doc/zmq_proxy_steerable.txt for more information.
* Add new autoconf --disable-libunwind option to stop building with libunwind
even if it is available.
* Add new autoconf --disable-Werror option to avoid building with the Werror
flag.
* Use pkg-config as the first method for finding and building with external
optional dependencies such as libnorm, libpgm and gssapi.
* On Posix platform where the feature is available, name the ZMQ background
threads to simplify debugging: "ZMQbg/<num_thread>"
* Improve performance of zmq_poller_* (and zmq_poll and zmq_proxy when building
with DRAFT APIs enabled).
* The TCP unit tests have been refactored to bind and connect to random ports
rather than hard-coded ones, to allow running tests in parallel.
There are 6 exceptions where it is necessary to use an hard-coded port to
test specific code paths that would not be exercised when binding to a
wildcard port. These are listed in tests/testutil.hpp so that distributions
can easily patch them if they wish to and so that they can be unique across
all the tests, allowing parallel runs.
The IPC unit tests have been changed as well to use unique socket file names
per test, where before there were some clashes.
* Fixed 2349 - fix building with libsodium when using CMake
* Fixed 2334 - do not assert when tuning socket options fails due to network
errors, but simply retry again when connecting or send a socket monitor

implementation) instead of Libsodium, and fix race condition when using
multiple ZMQ contexts with Tweetnacl

0MQ version 4.2.1 stable, released on 2016/12/31
=============================================
* New DRAFT (see NEWS for 4.2.0) Socket Monitor events:
- ZMQ_EVENT_HANDSHAKE_SUCCEED
- ZMQ_EVENT_HANDSHAKE_FAILED
These events trigger when the ZMTP security mechanism handshake is
completed. See doc/zmq_socket_monitor.txt for more information.
* New DRAFT (see NEWS for 4.2.0) Context options:
- ZMQ_MSG_T_SIZE
See doc/zmq_ctx_get.txt for more information.

0MQ version 4.2.0 stable, released on 2016/11/04
=============================================
* For Pieter. Thanks for making all of this possible.
"Tell them I was a writer.
A maker of software.
A humanist. A father.
And many things.
But above all, a writer.
Thank You. :)"
- Pieter Hintjens
* This release introduces new APIs, but it is ABI compatible with
libzmq 4.1.2 and up.
* Note for ARM and SPARC users: an alignment problem in zmq_msg_t that could in
some cases and on some CPUs cause a SIGBUS error was solved, but it requires
a rebuild of your application against the 4.2.0 version of include/zmq.h.
To clarify, this change does not affect the internals of the library but only
the public definition of zmq_msg_t, so there is no ABI incompatibility.
* Security with Curve is now available by default thanks to Tweetnacl sources:
https://tweetnacl.cr.yp.to/index.html
Libsodium is still fully supported but has to be enabled with the build flag
--with-libsodium. Distribution and package maintainers are encouraged to use
libsodium so that the security implementation can be audited and maintained
separately.
* New Context options:
- ZMQ_MAX_MSGSZ
- ZMQ_BLOCKY
See doc/zmq_ctx_set.txt and doc/zmq_ctx_get.txt for details.
* New Socket options:
- ZMQ_HANDSHAKE_IVL
- ZMQ_SOCKS_PROXY
- ZMQ_XPUB_NODROP
- ZMQ_XPUB_MANUAL
- ZMQ_XPUB_WELCOME_MSG
- ZMQ_STREAM_NOTIFY
- ZMQ_INVERT_MATCHING
- ZMQ_HEARTBEAT_IVL
- ZMQ_HEARTBEAT_TTL
- ZMQ_HEARTBEAT_TIMEOUT
- ZMQ_XPUB_VERBOSER
- ZMQ_CONNECT_TIMEOUT
- ZMQ_TCP_MAXRT
- ZMQ_THREAD_SAFE
- ZMQ_MULTICAST_MAXTPDU
- ZMQ_VMCI_BUFFER_SIZE
- ZMQ_VMCI_BUFFER_MIN_SIZE
- ZMQ_VMCI_BUFFER_MAX_SIZE
- ZMQ_VMCI_CONNECT_TIMEOUT
- ZMQ_USE_FD
See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
* New CURVE helper function to derive z85 public key from secret key:
zmq_curve_public
* New cross-platform atomic counter helper functions:
zmq_atomic_counter_new, zmq_atomic_counter_set, zmq_atomic_counter_inc,
zmq_atomic_counter_dec, zmq_atomic_counter_value, zmq_atomic_counter_destroy
See doc/zmq_atomic_*.txt for details.
* New DRAFT APIs early-release mechanism. New APIs will be introduced early
in public releases, and until they are stabilized and guaranteed not to
change anymore they will be unavailable unless the new build flag
--enable-drafts is used. This will allow developers and early adopters to
test new APIs before they are finalized.
NOTE: as the name implies, NO GUARANTEE is made on the stability of these APIs.
They might change or disappear entirely. Distributions are recommended NOT to
build with them.
New socket types have been introduced in DRAFT state:
ZMQ_SERVER, ZMQ_CLIENT, ZMQ_RADIO, ZMQ_DISH, ZMQ_GATHER, ZMQ_SCATTER,
ZMQ_DGRAM
All these sockets are THREAD SAFE, unlike the existing socket types. They do
NOT support multipart messages (ZMQ_SNDMORE/ZMQ_RCVMORE).
ZMQ_RADIO, ZMQ_DISH and ZMQ_DGRAM also support UDP as transport,
both unicast and multicast. See doc/zmq_udp.txt for more details.
New methods to support the new socket types functionality:
zmq_join, zmq_leave, zmq_msg_set_routing_id, zmq_msg_routing_id,
zmq_msg_set_group, zmq_msg_group
See doc/zmq_socket.txt for more details.
New poller mechanism and APIs have been introduced in DRAFT state:
zmq_poller_new, zmq_poller_destroy, zmq_poller_add, zmq_poller_modify,
zmq_poller_remove, zmq_poller_wait, zmq_poller_wait_all, zmq_poller_add_fd
zmq_poller_modify_fd, zmq_poller_remove_fd
and a new supporting struct typedef: zmq_poller_event_t
They support existing socket type, new thread-safe socket types and file
descriptors (cross-platform).
Documentation will be made available in the future before these APIs are declared
stable.
New cross-platform timers helper functions have been introduced in DRAFT state:
zmq_timers_new, zmq_timers_destroy, zmq_timers_add, zmq_timers_cancel,
zmq_timers_set_interval, zmq_timers_reset, zmq_timers_timeout,
zmq_timers_execute
and a new supporting callback typedef: zmq_timer_fn
* Many, many bug fixes. The most important fixes are backported and captured in the
4.1.x and 4.0.x changelogs.

Move PKGREVISION to the standard location.
Clang needs C++11 as well.
Exactly specify the location of libsodium to configure.
Use mk/compiler.mk and CC_VERSION to check compiler instead of PKGSRC_COMPILER.
Link against security/libsodium so that CURVE security becomes available. Conditionalize C++ standard on the compiler being used (the curve code in zeromq uses "long long" which is not vali in C++98).
Update zeromq to 4.0.4. 0MQ version 4.0.4 stable, released on 2014/03/10 ================================================ Bug Fixes --------- * Fixed #909; out of tree build issue on Linux. * Fixed #888; hangs on terminate when inproc connected but never bound. * Fixed #868; assertion failure at ip.cpp:137 when using port scanner. * Fixed #818; fix timestamp counter on s390/s390x. * Fixed #817; only export zmq_* symbols. * Fixed #797; fixed setting TCP keepalive on Windows. * Fixed #775; compile error on Windows. * Fixed #763; when talking to a ZMTP v1 peer (libzmq 2.2), a socket would send an extra identity frame at the start of the connection. * Fixed LIBZMQ-576 - Crash closing a socket after zmq_msg_send returns EAGAIN (reverts LIBZMQ-497) * Fixed LIBZMQ-584; subscription filters getting lost on reconnection.
Update zeromq to 4.0.3.
0MQ version 4.0.3 stable, released on 2013/11/24
================================================
Bug Fixes
---------
* Fixed test_many_sockets case, which failed when process socket limit
was 1024.
0MQ version 4.0.2 stable, released on 2013/11/24
================================================
Bug Fixes
---------
* Fixed LIBZMQ-583 - improved low-res timer for Windows
* Fixed LIBZMQ-578 - z85_decode was extremely slow
* Fixed LIBZMQ-577 - fault in man pages.
* Fixed LIBZMQ-574 - assertion failure when ran out of system file handles
* Fixed LIBZMQ-571 - test_stream failing in some cases
* Fixed LIBZMQ-569 - Socket server crashes with random client data and when
talking to 2.2 versions
* Fixed LIBZMQ-39 - Bad file descriptor during shutdown
* Pulled expected failing test_linger.cpp from release
* Reduced pause time in tests to allow "make check" to run faster
0MQ version 4.0.1 stable, released on 2013/10/08
================================================
Changes
-------
* Updated CURVE mechanism to track revised RFC 27 (INITIATE vouch).
The INITIATE command vouch box is Box[C',S](C->S') instead of
Box[C'](C->S), to reduce the risk of client impersonation, as per
https://codesinchaos.wordpress.com/2012/09/09/curvecp-1/.
* Fixed LIBZMQ-567, adding abstract namespaces for IPC sockets on Linux.
Converts an initial strudel or "at sign" (@) in the Unix socket path to
a NULL character ('\0') indicating that the socket uses the abstract
namespace instead of the filesystem namespace. For instance, binding a
socket to 'ipc://@/tmp/tester' will not create a file associated with
the socket whereas binding to 'ipc:///tmp/tester' will create the file
/tmp/tester. See issue 567 for more information.
* Added zmq_z85_encode and zmq_z85_decode to core libzmq API.
* Added zmq_curve_keypair to core libzmq API.
* Bumped library ABI version to 4:0:1.
Bug fixes
---------
* Fixed some build/test errors on OS/X + Clang++.
* Fixed LIBZMQ-565, typo in code.
* Fixed LIBZMQ-566, dealer-to-router connections sometimes failing.
* Fixed builds for AIX, MSVC 2008, OS/X with clang++, Solaris.
* Improved CURVE handshake error handling.
0MQ version 4.0.0 (RC1), released on 2013/09/20
===============================================
Major changes
-------------
* New wire level protocol, ZMTP/3.0, see http://rfc.zeromq.org/spec:23.
Does not yet implement the SUBSCRIBE, CANCEL, PING, and PONG commands.
* New security framework, from plain user+password to strong encryption,
see section below. See http://hintjens.com/blog:49 for a tutorial.
* New ZMQ_STREAM socket type for working as a TCP client or server. See:
tests/test_stream.cpp.
Improvements
------------
* You can now connect to an inproc:// endpoint that does not already
exist. This means inproc:// no longer needs careful set-up, but it may
break code that relied on the old behaviour. See:
tests/test_inproc_connect.cpp.
* Libzmq now checks socket types at connection time, so that trying to
connect a 'wrong' socket type will fail.
* New zmq_ctx_shutdown API method will shutdown a context and send ETERM
to blocking calls, without blocking. Use zmq_ctx_term to finalise the
process.
* The regression test suite has been significantly extended and improved.
* Contexts can now be terminated in forked child processes. See:
tests/test_fork.cpp.
* zmq_disconnect now respects the linger setting on sockets.
* New zmq_send_const API method to send constant data (without copying).
See: tests/test_inproc_connect.cpp.
* Added CMake support for static libraries.
* Added test cases for socket semantics as defined in RFCs 28, 29, 30, 31.
See: tests/test_spec_*.cpp.
* New socket option, ZMQ_PROBE_ROUTER triggers an empty message on connect.
See: tests/test_probe_router.cpp.
* New socket option, ZMQ_REQ_CORRELATE allows for correlation of replies
from a REP socket. See: tests/test_req_correlate.cpp.
* New socket option, ZMQ_REQ_RELAXED, lets you disable the state machine
on a REQ socket, so you can send multiple requests without waiting for
replies, and without getting an EFSM error. See:
tests/test_req_relaxed.cpp.
* New socket option, ZMQ_CONFLATE restricts the outgoing and incoming
socket buffers to a single message. See: tests/test_conflate.cpp.
Deprecated Options
------------------
* ZMQ_IPV4ONLY deprecated and renamed to ZMQ_IPV6 so that options are
consistently "off" by default.
* ZMQ_DELAY_ATTACH_ON_CONNECT deprecated, and renamed to ZMQ_IMMEDIATE.
See: tests/test_immediate.cpp.
Security Framework
------------------
Based on new ZMTP wire level protocol that negotiates a security
"mechanism" between client and server before exchanging any other data.
Security mechanisms are extensible. ZMTP defines three by default:
* NULL - classic ZeroMQ, with no authentication. See
http://rfc.zeromq.org/spec:23.
* PLAIN - plain-text username + password authentication. See
http://rfc.zeromq.org/spec:24.
* CURVE - secure authentication and encryption based on elliptic curve
cryptography, using the Curve25519 algorithm from Daniel Bernstein and
based on CurveCP's security handshake. See http://rfc.zeromq.org/spec:25,
http://rfc.zeromq.org/spec:26, and http://curvecp.org.
Authentication is done by pluggable "authenticators" that connect to libzmq
over an inproc endpoint, see http://rfc.zeromq.org/spec:27.
Socket options to configure PLAIN security on client or server:
* ZMQ_PLAIN_SERVER, ZMQ_PLAIN_USERNAME, ZMQ_PLAIN_PASSWORD. See
tests/test_security_plain.
Socket options to configure CURVE security on client or server:
* ZMQ_CURVE_SERVER, ZMQ_CURVE_PUBLICKEY, ZMQ_CURVE_SECRETKEY,
ZMQ_CURVE_SERVERKEY. See tests/test_security_curve.cpp.
Socket options to configure "domain" for ZAP handler:
* ZMQ_ZAP_DOMAIN, see tests/test_security_null.cpp.
Support for encoding/decoding CURVE binary keys to ASCII:
* zmq_z85_encode, zmq_z85_decode.
Other issues addressed in this release

Behavior now is to return -1 at zmq_setsockopt in this situation. * Fixed issue 207, assertion failure in zmq_connecter.cpp:48, when an invalid zmq_connect() string was used, or the hostname could not be resolved. The zmq_connect() call now returns -1 in both those cases. * Fixed issue 218, sockets not opened with SOCK_CLOEXEC, causing fork/exec to sit on sockets unnecessarily. * Fixed issue 250, build errors on Windows. * Fixed issue 252, assertion failure in req.cpp:87 and req.cpp:88. * Fixed issue 261, assertion failure in kqueue.cpp:76 on OS/X. 0MQ version 2.1.9 (Stable), released on 2011/08/29 ================================================== Bug fixes --------- * Fixed issue 240, assertion failure in pgm_socket.cpp:437. * Fixed issue 238, assertion failure in zmq.cpp:655, when zmq_poll is used on an empty set, on Windows. * Fixed issue 239, assertion failure in zmq.cpp:223, when ZMQ_SWAP was used with explicit identities and multiple SUB sockets. * Fixed issue 236, zmq_send() and zmq_recv() did not always return error conditions such as EFSM properly. This bug was introduced in version 2.1.8 by the backport of changes for issue 231. Building -------- * 0MQ support for Android added (Bill Roberts, Mikko Koppanen). 0MQ version 2.1.8 (RC), released on 2011/07/28 ============================================== Bug fixes --------- * Fixed issue 223, assertion failure in tcp_connecter.cpp:300 when connecting to a server that is on an unreachable network (errno is equal to ENETUNREACH). * Fixed issue 228, assertion failure at rep.cpp:88 when HWM was reached. * Fixed issue 231, assertion failure at mailbox.cpp:183 when too many pending socketpair operations were queued (major backport from 3.0). * Fixed issue 234, assertion failure at mailbox.cpp:77 when Ctrl-C was used (only affected git master following backport for 231). * Fixed issue 230, SIGPIPE killing servers when client disconnected, hit OS/X only. Note: this release was renamed "release candidate" due to issue 236, fixed in 2.1.9.
Update zeromq to 2.1.7. 0MQ version 2.1.7 (Stable), released on 2011/05/12 ================================================== Bug fixes --------- * Fixed issue 191, message atomicity issue with PUB sockets (an old issue). * Fixed issue 199 (affected ROUTER/XREP sockets, an old issue). * Fixed issue 206, assertion failure in zmq.cpp:223, affected all sockets (bug was introduced in 2.1.6 as part of message validity checking). * Fixed issue 211, REP socket asserted if sent malformed envelope (old issue due to abuse of assertions for error checking). * Fixed issue 212, reconnect failing after resume from sleep on Windows (due to not handling WSAENETDOWN). * Properly handle WSAENETUNREACH on Windows (e.g. if client connects before server binds). Changes ------- * Runtime checking of socket and context validity, to catch e.g. using a socket after closing it, or passing an invalid pointer to context/socket methods. * Test cases moved off port 5555, which conflicts with other services. * Clarified zmq_poll man page that the resolution of the timeout is 1msec.
Update zeromq to 2.1.6. 0MQ version 2.1.6 (Stable), released on 2011/04/26 ================================================== Bug fixes --------- * Fixed memory leak with threads on Windows. * Assert during SUB socket termination fixed. Changes ------- * Checks zmq_msg_t validity at each operation. * Inproc performance tests now work on Windows. * PGM wire format specification improved in zmq_pgm(7) * Added thread latency/throughput performance examples. * Added "--with-system-pgm" configure option to use already installed OpenPGM. 0MQ version 2.1.5 (Broken), released on 2011/04/20 ================================================== Note that this version contained a malformed patch and is not usable. It is not available for download, but is available in the git via the 2.1.5 tag. 0MQ version 2.1.4 (Stable), released on 2011/03/30 ================================================== Bug fixes --------- * Fix to OpenPGM which was asserting on small messages (Steven McCoy). Changes ------- * Upgraded OpenPGM to version 5.1.115 (Pieter Hintjens). * OpenPGM build changed to not install OpenPGM artifacts. 0MQ version 2.1.3 (Stable), released on 2011/03/21 ================================================== Bug fixes --------- * Fix to PUSH sockets, which would sometimes deliver tail frames of a multipart message to new subscribers (Martin Sustrik). * Fix to PUB sockets, which would sometimes deliver tail frames of a multipart message to new subscribers (Martin Sustrik). * Windows build was broken due to EPROTONOSUPPORT not being defined. This has now been fixed (Martin Sustrik). * Various fixes to make OpenVMS port work (Brett Cameron). * Corrected Reference Manual to note that ZMQ_LINGER socket option may be set at any time, not just before connecting/binding (Pieter Hintjens). * Fix to C++ binding to properly close sockets (Guido Goldstein). * Removed obsolete assert from pgm_socket.cpp (Martin Sustrik). Changes ------- * Removed stand-alone devices (/devices subdirectory) from distribution. These undocumented programs remain available in older packages (Pieter Hintjens). * OpenPGM default rate raised to 40mbps by default (Steven McCoy). * ZMQ_DEALER and ZMQ_ROUTER macros provided to ease upgrade to 0MQ/3.0. These are scheduled to replace ZMQ_XREQ and ZMQ_XREP (Pieter Hintjens). * Added man page for zmq_device(3) which was hereto undocumented (Pieter Hintjens). * Removed zmq_queue(3), zmq_forwarder(3), zmq_streamer(3) man pages (Pieter Hintjens). OpenPGM Integration ------------------- * Upgraded OpenPGM to version 5.1.114 (Steven McCoy, Mikko Koppanen). * Build system now calls OpenPGM build process directly, allowing easier future upgrades of OpenPGM (Mikko Koppanen). * Build system allows configuration with arbitrary versions of OpenPGM (./configure --with-pgm=libpgm-x.y.z) (Mikko Koppanen). * OpenPGM uses new PGM_ODATA_MAX_RTE controlling original data instead of PGM_TXW_MAX_RTE covering entire channel (Steven McCoy). Building -------- * 0MQ builds properly on FreeBSD (Mikko Koppanen). 0MQ version 2.1.2 (rc2), released on 2011/03/06 =============================================== Bug fixes --------- * 0MQ now correctly handles durable inproc sockets; previously it ignored explicit identities on inproc sockets. * Various memory leaks were fixed. * OpenPGM sender/receiver creation fixed. 0MQ version 2.1.1 (rc1), released on 2011/02/23 =============================================== New functionality ----------------- * New socket option ZMQ_RECONNECT_IVL_MAX added, allows for exponential back-off strategy when reconnecting. * New socket option ZMQ_RECOVERY_IVL_MSEC added, as a fine-grained counterpart to ZMQ_RECOVERY_IVL (for multicast transports). * If memory is exhausted, 0MQ warns with an explicit message before aborting the process. * Size of inproc HWM and SWAP is sum of peers' HWMs and SWAPs (Douglas Greager, Martin Sustrik). Bug fixes --------- * 0MQ no longer asserts in mailbox.cpp when multiple peers connect with the same identity. * 0MQ no longer asserts when rejecting an oversized message. * 0MQ no longer asserts in pipe.cpp when the swap fills up. * zmq_poll now works correctly with an empty poll set. * Many more. Building -------- * 0MQ now builds correctly on CentOS, Debian 6, and SunOS/gcc3. * Added WithOpenPGM configuration into MSVC builds. Known issues ------------ * OpenPGM integration is still not fully stable. 0MQ version 2.1.0 (Beta), released on 2010/12/01 ================================================ New functionality ----------------- * New semantics for zmq_close () and zmq_term () ensure that all messages are sent before the application terminates. This behaviour may be modified using the new ZMQ_LINGER socket option; for further details refer to the reference manual. * The new socket options ZMQ_FD and ZMQ_EVENTS provide a way to integrate 0MQ sockets into existing poll/event loops. * Sockets may now be migrated between OS threads, as long as the application ensures that a full memory barrier is issued. * The 0MQ ABI exported by libzmq.so has been formalised; DSO symbol visibility is used on supported platforms to ensure that only public ABI symbols are exported. The library ABI version has been set to 1.0.0 for this release. * OpenPGM has been updated to version 5.0.92. This version no longer depends on GLIB, and integration with 0MQ should be much improved. * zmq_poll() now honors timeouts precisely, and no longer returns if no events are signaled. * Blocking calls now return EINTR if interrupted by the delivery of a signal; this also means that language bindings which previously had problems with handling SIGINT/^C should now work correctly. * The ZMQ_TYPE socket option was added; this allows retrieval of the socket type after creation. * Added a ZMQ_VERSION macro to zmq.h for compile-time API version detection. * The ZMQ_RECONNECT_IVL and ZMQ_BACKLOG socket options have been added. Bug fixes --------- * Forwarder and streamer devices now handle multi-part messages correctly. * 0MQ no longer asserts when malformed data is received on the wire. * 0MQ internal timers now work correctly if the TSC jumps backwards. * The internal signalling functionality (mailbox) has been improved to automatically resize socket buffers on POSIX systems. * Many more. Building -------- * 0MQ now builds correctly with many more non-GCC compilers (Sun Studio, Intel ICC, CLang). * AIX and HP-UX builds should work now. * FD_SETSIZE has been set to 1024 by default for MSVC builds. * Windows builds using GCC (MinGW) now work out of the box. Distribution ------------ * A simple framework for regression tests has been added, along with a few basic self-tests. The tests can be run using "make check".
